I consider this specific issue resolved.

As far as ports detecting if options have been set in make.conf, that is a 
larger issue than with just one port. The ports infrastructure relies on 
settings in make.conf that do not negatively interfere with the 
infrastructure or ports build process. Options address this issue though if 
a person wishes to set a variable in make.conf for an application outside 
of the ports infrastructure which could have a negative impact on a build, 
it is possible for ports to unset any possible make or environment variable 
that would be used during a build to avoid this situation.

I'm CCing this to FreeBSD-ports@ to generate some discussion about the 
issue in general and BCC to GNATS to maintain a record of this in the 
database.
